Application tiled August 23, 1910. Serial No. 578,498.

To all whom "it may concern:

Be it known Athat I, RICHARD P. JOHNSON, a citizen of theUnited States, and a resident of the city of New York, borough of 'Brooklyn, in the county of Kings and State of New York, haveinvented a new and lmproved Sugar-Remover for Centrifugal Machines, of which the following is a full, clear, and exact description.

This invention relates to a new and improved device for removing sugar deposited by ,centrifugal yforce on the walls of sugar separators.'

It has been the practice in many sugar refineries to remove the sugar from the basket or bowl, either by having a permanently fixed paddle in the bowl which removes the sugar while the separating operation is going on, or by stoppingthe bowl after a certain period of operation, and removing the sugar by hand, with the aid of paddles. The former method is exceedingly dangerous, because of the high speed at which the separators run, and the second method is laborious and consumes considerable time.

An'object, therefore, of this invention is to provide a device which can be used intermediate the separating operations, with a saving of at least twenty-five per cent. in labor and time, and with the least detriment to the separator itself.

A further object of this invention is to provide a sugar remover which can be adjusted from an inoperative position'without the bowl to an'operativeposition within the bowl, and which can be further adjusted vertically, so as to remove the sugar'from all parts of the bowl.

These and further objects together with the construction and combination of parts, will be more fully described hereinafter and particularly set forth in the claims.

- Reference may be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference denote corresponding parts in all-the views, and in which- Figure 1 is a fragmentary view in sectional elevation, of a centrifugal sugar separator, y,showing my device attached thereto, and showing in f ull and dotted lines its position within and without the separating basket; Fig. 2 is a fragmentary plan View; Fig. 3 is an enlarged detached view in clevation, of the bracket; Fig. 4 is a vertical section on the line 4 4 of Fig. 3; Fig. 5 1s a detached top plan view of the scraper; and Fig. 6 is a fragmentary side view/,in elevation, of the adjustable paddle of the sugar separator.

Referringv more particularly to the 4separate parts, 1 indicates a framework, within which is rotatably mounted a separating bowl or basket Q, which may be of any suitable character, and 'which is adapted to receive the sugar separated b v centit'ugal force from the moisture, on its peripheral wall.

Secured to the frame 1 in any suitable manner, as by means of bolts 3, there is ratentednpi. es. 1911.

provided a supporting member 4, which'` has j a hinge connection 5 with a bracekt 6,v so that the bracket 6 can be swung from the full linevposition illustra-ted in Fig. l to the dotted line positionalso illustrated in- Fig. 1. The bracket G is adapted toy project f over the inner edge of the bowl or basket vf2, and is provided at its projecting end with a vertically extending opening, in which is mounted a sleeve 7. This sleeve 7 is broken away at its lower end4 on two sides, as will be seen at the point marked 8.

Slidingly mounted in the sleeve 7 which is provided with a vertically extending opening, there is provided au implement 9,which consists of a bar 10. and a scraper l1. The bar 10 is slidinglyY mounted in the sleeve 7, so that the scraper can be adjusted to any position in the bowl. For the purpose of j'iermitting the scraper 11 to be 4adjusted toward and from thc surface of the bowl, the sleeve 7 is pivotally mounted in the bracket 6 by means of screw bolts 12, which pass through openings in the sides of the 'down from the bracket G on opposite sides of the sleeve 7. -ln order to prevent the scraper 11 from coming' in contact with the bottom, there is provided a limit stop 15, which is adapted to limit motion of the bar 10.

lt will be yseen by referring to 5 and'y 6. that the scraper 11 consists of a 'body portion 16, curved so as to bring the front end thereof at an acute angle to the peripheral surface of the-.bowl or basket The end of the body portion 16 which will be juxtaposed to the wall of tbc basket is provided th e downward blade 18, which wood, so as not to injure the screen of which the sides of 'most separator baskets\ are -with an enlargement 17, tojwhich is 4removably and adjustably secured a paddle or referably is formed of formed. In this case'it will be seen that the blade or paddle 18 is provided with a slot 19, which is engaged by a bolt 20, passing therethrough, `and being-secured to the en-y largement 17. A washer 21 maybe interposed between tlie bolt and the blade,so as y to make the locking engagement more positive. It will be seen that by this means the paddle or blade 18 can be adjusted on the body portion 16 totake up the wear incident to its use. y

The operation of the device will belreadily understood when taken in connect-ion with the above description,

During the separating operation, thelbowl Q is rotated' at a speed of about 800 revolutions per minute, which speed is suilicient to` I `drain thc liquid-ofthe saccharine matter blade 18 becomes slightly Worn, the vpivotal fruu'i the sugar by centrifugal foi-cc. 'Duri ing this operation, the remover islocated in the position illustratedbyydotted lines in Fig. 1. lV'hen a sufficient amount of sugar:

has been collected on the side of the 4bowl or basket, the power is shut o and the brake applied to the basket, so that the number of revolutions is reduced to about ten or twelve per minute. The remover is then swung from the dotted line position Ito the full lineosition, and the scraper is lowered by a vaborer gradually, as the sugar is removed from top to'bottom. After the paddle. or

suppoi'tot the sleeve 7 will permit the in the removing of sugar from centri 5,0

scraper to be adjustedcloser to thev basketto take up this wear. Then this wear becomes excessive, the paddle or blade can be adjusted by looseningl the bolt Q0. and movingl the paddlefart-her outward. This latter operation however, is rarely necessary, as the swinging movement ofthe implement 9 will allow for all ordinary wear. It will thus be seen that'therev f s'provided a device which" will effect' a great savingin timeand labor ugal separators. f. AI Vhile I have shown one embodiment 'of my invention, I do not wish to be limitedvto the specific details but desirel to beprotected in variousxchanges, alterations andl modifications which may come withinthescop'e' if the appended claims.` i
